FLUID VACUUM FEED DEVICE.

Application filed August 18, 1920. Serial No. 404,443.

To all whom it may concern:

Be it known that I, LOGAN N. KELLEY, a citizen of the United States,residing in New York, in the, county of New York and State of New York,have invented certain new and useful Improvements in Fluid Vacuum FeedDevices, of which the following is a specification.

My present invention relates to an improvement in vacuum fluid feedcontrol mechanisms for motor vehicles, motor boats and the like.

One object of my invention is to provide a vacuum fluid feed controlmechanism which. shall be simplein construction, and reliable inoperation, and of extremely compact form.

Another object is to provide a vacuum fluid feed control mechanismhaving means for viewing the interior of the device for determining theamount of fluid therein and the action of the parts thereof.

Another object is to provide a vacuum feed control mechanism which maybe 10- cat-ed on or adjacent to the dash of the mo tor vehicle in plainsight of the operator, and which has means for viewing the interior ofthe device for determining the amount of fuel therein without liftingthe hood of the engine, and to confirm the proper action of the controlmechanism and the flow ofthe fuel.

A feature of my device is the use of an oscillatable valve havingoppositely disposed closure means for sequentially open ing and closingthe valve ports.

Another feature of my device is the use of a valve oscillatable by floatmeans and having oppositely disposed closure means for sequentiallyopening and closing the valve ports.

Another feature of my device is the use of a valve having oppositelydisposed closure means for sequentially opening and closing the valveports, the valve being oscillatable by a float arranged for imparting astarting movement or jar to the valve for facilitating the oscillationof the valve by the float.

Another feature of my device is the use of a valve having oppositelydisposed closure means for sequentially opening and closing the valveports and oscillata'ble by a float, the valve having stop means forengagement therewith of means actuated by thefloat for oscillating thevalve to open or to close sequentially the valve ports by movement ofthe float.

Another important feature of my device is the few and simple operativeparts whereby the ports are sequentially opened or closed to admit fuelor to stop the flow thereof to the container.

These, and other objects, features and capabilities of my invention willbe disclosed in the course of the following description.

In the accompanying drawings which form part of this specification,Figure 1, is a side elevation of my device with the side casing removed.

Figure 2, is an end elevation of my device with the end casing partlybroken away.

Figure 8, is a fragmental view showing the valve mechanism.

Figure 3, is a view, similar to Fig. 3, showing by dotted lines thefloat in two positions for indicating the movement of the floatirrespective of the valve, and showing the means, or bent arm, actuatedby the float, in two positions of contact with the stop means on thevalve, for oscillating the valve by movement of the float.

Similar letters or numerals refer to similar parts throughout theseveral views.

The embodiment of my invention shown in the drawings comprises a tankgenerally denoted by A, having a main compartment B and a secondarycompartment C.

The cover or top 10 of the compartment B is removably attached to thesides of the tank 11 as by the screws 11 engaging the side extensions12. The cover or top 10 has on. the exterior thereof, preferably castthereon, apertured lugs 13, 1a and 15, and has on the interior thereofarranged in alinement with the lugs 14 and 15, and preferably cast onthe cover or top 10, an inwardly extending bracket 16. The lug 13 has athreaded exterior for engagement therewith of a nut 17 for operativelyconnecting to the lug 13 a pipe 18 communicating with the source offluid supply, the aperture 19 of the lug 13 registering with a passage20 tln'ough the cover or top 10.

The lug 14: has a threaded interior which communicates by the passage 21through the cover or top 10 with the suction bore or suction port in thebracket 16, which suction bore or suction port opens into the interiorof the main compartment 13, the bracket 16 also being prdvidedg with anatmosphere, bore or port later mentioned, the plane face of the brackethaving said bores or ports therethrough constituting a valve section.

The pipe 23 which communicates with the intake manifold of an internalcombustion engine E, is received in the threadedinterior of the lug 14.t

The apertured lug 15 is open to the atmosphere and communicates throughpassage 24 in theeover or top 10 with the atmosphere bore or port 25before mentioned in the bracket 16, which atmosphere bore or port opensinto the interior the main compartment B, I i I The lug '15 has anextension or shoulder 26 having the her-e27 therein which communicatesthrough a passage 28 in the, cover or top 10 with aii aperture29 in theextended end, of the bracket 16, the atmosphere pipe 39 being receivedin the aperture and'eX- tending through the bottom 31 of the compartmentBfintothe secondary compartment C. v I I The pin 32 is pivoted in thebracket 16, being held in place by the nut 33, and is provided at itsend opposite to the bracket 16 with a head 34, which preferably isintegral with the pin 32.

The valve disk or plate 35 preferably is of the segmental shape shownand is provided with a cut out space or bridged por-,

tion 36 having a solid surface portion 37 adjacent to one side thereofand a solid Sill:

face portion 38 adjacent to the otherside thereof. i I

The valve disk or plate 35 is loosely mounted on the pin 32 adjacent tothe inner face of the bracket 16, and is provided with oppositelydisposed lugsor stops 39 and- 40, thelug or stop40- having a threadedhole for receiving therein an adjustable screw 41' extendingtransversely to the lugs or stops,

39 and 40 and limiting or filling in the space between these lugs; orstops; The helix spring 42 is arranged around the pin 32, one endthereof being seated in the pin 32 and the other end being seated in thevalve disk or plate 35, the spring 42 serving tohold the valve disk orplate 35in position adjacent to thebracket 16,, for opening or closing,in prearranged sequence the suction port 22 and atmosphere port 25 ofthe bracket.

The bail arm 43 preferably is integral with the head 34 of the pin 32and carries the bail 44 in which is, swung the float 45.

But it is obviousjthat the bail arm 43 could:

as "Well be extended as an arm fixedly secured V to the float 45, thebail 44 being omitted, and

the float 45 carried directly by this arm.

The valve disk actuating finger 46 extends from the head34 onthe sidethereof opposite to, the bail arm 43, and substantially in linetherewith, and is provided with a transversely bent end 4?, parallel tothe pin 32', the end 4'7 being located between the lug 39 of the valvedisk or plate 35 and the inner end of the adjustable screw 41,

and being engageable with the lug 39- or the The pipe 49, has anupturned end 50 pro- 7 vided with a hinged cover or valve 51, movable toopen. p sition by pressure upon its under side. v

The bottom 52. of the secondary compartment C is removably attached to,the sides of the tankor container, A as. by screws 53 engaging the sideextensions 5,4,"the bottom 52 being provided with a suitable outlet suchas 55 to the carburetter of the internal combustion engine, andprovided, with a suitable drain such as 56.

The side of the main compartment B is provided with an opening or window57, covered by glass or other suitable transparent material, so arrangedas to permit a view therethrough of the float 43, when the float is ineither its uppermost or lowermost PQS 0 In operation, the float 45 beingin its 35 the atmosphere port or bore 25 being:

covered or'elosed by the-solid surfacepor' tion 38'. 7 Operation of the.engine E ex hausts by means of the pipe 23, the air from the compartmentB by means of the port or bore 22,-thereby causing an indrawing or flowoffluid into the compartment B by means of the pipe 18 from the sourceof supply.

Due to inflow offluidtheiloat 45, is raised from its lowermost position,until by up: ward movement of the float the bent end 47 of the finger46.1eleases its contact or engagement with the lug or stop 39 of, thevalve diskor plate 35, and oscillates or swingsinto contact with theadjustable screw 4l,'thereby oscillating or movingthe vaivedisk or-plate'35, so that the solidsurface portion 37 covers or closesthesuction portor bore 22 and ;the

atmosphere port or bore 25 is opened oriex posed bythe cut out orbridgedportion 36. The admiss on of atmospheric air pressures throughthe port or bore 25 into the com partn ent B permits the fluid to flowinto corn- 1 partment C through the pipe .49 and'valve 51, theatmosphere p1pe 30 be ng always open, thereby venting the compartment C,and the fluid being conducted by the outlet 5-l to the carburettor ofthe engine. As the float i5 is lowered, due to outflow of the fluid fromthe compartment B, the bent end at? of the flnger 4C6 releases itscontact with the adjustable screw i1 and oscillates or swings intocontact with the lug or stop 39, thereby moving the valve disk or plate35 to cover the atmosphere port or bore 25 and to open the suction portor bore 22, or to the first described position. The inertia of the floattends to bring the bent finger-end l7 into contact with the lug or stop39 or r the screw il, as the case may be, with suiiicient jarring effectto prevent sticking ot the valve disk or plate 35 in its movements, andthe screw 41 is adjustable for regulating the distance of the swing ofthe bent finger-end 47 for contact with the lug or stop 39 or with thescrew ail, to give the desired impacting force to the bent finger-end47.

Having thus described my invention it should be understood that theremay be modifications thereof and variations therein without departingfrom the spirit of the invention or exceeding the scope of the appendedclaims.
